DEVICE FOR CUTTING TUBULAR METAL SHELLS.

SPECIFICATION forming part of Letters Patent No. 662,542, dated November27, 1900.

Application filed October 31,1899. Serial No. 735,370. (No model.)

To al?, whom 1125 may concern:

Be it known that LCHARLES S. MORsE,a citizen of the United States,residing at Waterbury, in the county of New Haven and State ofConnecticut, have invented a certain new and useful Device for CuttingTubular Metal Shells, of which the following is a specification.

My invention relates to a device or machine for cutting tubular metalshells to render them non-tubular. I will describe a device embodying myinvention and then point out the novel features thereof in the claims.

In the accompanying drawings, Figure l is a top view of a device forcutting tubular metal shells embodying my invention. Fig. 2 is an endelevation of the device shown in Fig. l. Fig. 3 is a side elevation,partly in vertical section. Fig. 4t is a detail sectional View of a partof the machine.

Similar characters of reference designate correspondingparts in all thefigures.

A represents a tubular metal shell, and a3 a continuous strip into whichthe shell is converted. This is done, preferably, by means of a pair ofcutter-disks l) b', carried by shafts b2 b3,which are suitably journaled above a bedplate or other base B. The critters are so arrangedrelatively to each other' as to shear the metal, and the lower disk balso serves as a bearing for one end ofthe shell A. The other end of theshell is supported in a carrier C, which is so mounted as to movelongitudinally of an adjustable frame C. By having this lframeadjustable I am enabled to feed the shell A to the cutter-disks at anincline, thereby enabling the cutters to cut the shell spirally. Thestrip as is taken up by a device which arranges it in a coil.

The shafts b2 b3 are rotated from the pulley B by means of the gears l,2, 3, 4, and 5, the gears 3, 4, and 5 being of such size as to permit ofthe cutter-disks b b' having the same surface speed should they be ofdifferent sizes. The shafts b2 b3 are also adjustably mounted in theirbearings, and this adjustment of the shafts and the cutter-disks carriedthereby permits of shells of different thicknesses of metal being cut bythem.

These shafts are also provided with thrust- 5o on a suitable base c5,and it is provided with a slot c6, through which a bolt 0"", carried by`said base c5, projects. The slot and bolt serve `as a means for holdingthe frame Cl in any adjusted position. The carrier C comprises a socket08, in which the end of a shell is held, and a yoke e9, the ends ofwhich slide on the rods c. The carrier is moved toward the cutter-disksto feed the metal shell thereto, and this may he done by means of a cordand weight. The carrieris held against the action ofthe Weight at thetime when a new shell is to be arranged in the machine by any suitableineans--as, for example, a pivoted hook C10, which engages with a fixedprojection C11. In order to prevent the shell being fed too far forward,a roller cl2, carried by the hase B, is provided near the cutter-disks.This roller may be an adjustable one and serve to regulate the width ofthe strip into which the shell is to be converted.

By having the frame C adjustable I am enabled to regulate the pitch ofthe cut. This is an important advantage, for the reason that in theformation of the tubular shell the bers of the metal are spirallyarranged and the pitch of the spiral can in a measure be controlledduring'the shells formation. It will be seen, therefore, that if theshell 'is cut on the same pitch of the fibers of the shell the reductionof the cross-section is more easily accomplished and better resultsobtained. As the shell is cut into a strip a roller 013 guides it to achannel or conduit CZ, and as it exits from the channel it passesbetween the rolls d d2. These rolls tend to straighten the stri p andalso to draw it through the channel and away from the cutters. A rollcl3, which is adjustable, serves to guide the strip downward onto aceiling-drum D.

A flange d4, that is spirally arranged about' the drum, serves to feedthe strip forward on the drum and arrange it in acoil thereon.

The dri-um D is iXed to a shaft d5, which is suitably journaled in anextension of the base B. This shaft is driven by means of a pulley d andintermediate gears 6, 7, and 8. The gear Sis loose on the shaft d5, andmotion lis preferably com municated to the shaft from the gear 8 bymeans of a friction device @Z7 of any well-known construction. Thepulley d6 is fixed to the shaft d8, on which the roll d2 is fixed, andmotion is communicated from this shaft to the shaft di, carrying theroll d', by means of the gears 6, 7, and 8. The shafts d8 and di areadjustable.

The drum D is shown as tapered to enable the strip t3 to be removed. Thestrip is prevented from leaving the drum by means of a ring e. This ringis removable from the drum, and it is held thereon bymeans of pins e,which project through openings provided in the wall of the drum. Thesepins have a sliding bearing in the radial arms e2 of the drum, and theyare reciprocated by means of the links e3, which are pivoted to a sleevee7, fixed to the shaft d5. The links es are moved by the links e5, whichare connected to a sliding head e6, a rod and handle e4 serving toreciprocate said head e6.

The operation of the device, briefly stated, is as follows: The shell Ais placed in position in the frame and the carrier O released in orderthat it may be moved forward by the weight to feed the shell. Prior tothe device being put in operation the frame C/ is adjusted so as to beinclined to the cutterdisks, as shown in Fig. l. The amount of theinclination to loe given the frame is determined by the pitch of thefibers in the metal shell. This inclination also permits of thecutter-disks giving a spiral cut to the shell. The device is thenstarted and the shell reduced to a strip, which is arranged or Wound ina coil by the ceiling device. The strip in this shape is what is termedstock metal and is ready for further treatment. The strip is designedparticularly for stock from which wire may be produced in any of thewell-known ways.

It will be seen, therefore, that my invention comprises means, first,for rendering a tubular shell non-tubular by cutting it into a metalstrip; second, means for supporting the shell and feeding it to thecutting means; third, adjusting said feeding and supporting means, oreither, in order to determine the pitch of the cut to be given theshell, and,

fourth, means for receiving the strip and arranging it so that it can beeasily handled.

lVhat I claim as my invention isl. The combination of a carriersupported on a frame and movable longitudinally thereof for supportingone end of a metallic shell, cutter-disks for cutting said shell one ofsaid disks serving as a bearing for the other end of said shell, and'means for moving the carrier toward the cutter-disks, substantially asdescribed.

2. The combination of rotarycutters, means for supporting a metallicshell said means com prisingaframe pivotally supported at one end andadjustable laterally at its opposite end, a carrier movablelongitudinally of said frame, and means for adjusting said frame.

3. In a device for cutting shells of metal, the combination ofcutter-disks between which the shell is cut, an adjustable frame,

a socket upon the frame for supporting one end of the shell, means formoving said socket toward the cutter-disks, and a device for coiling thestrip into which the shell is cut.

4L. In a device for cutting cylindrical shells, the combination ofcutterdisks between which the shell is cut and one of which supports oneend of the shell, means for supporting the other end of the shell, meansfor feeding said shell longitudinally to the cutterdisks, and a devicefor regulating the amount of said feed.

5. In a device for cutting shells of metal, the combination of cutterdisks between which the shell is cut, means for feeding said shell tothe disks, an adjustable frame supporting said means, and a device forregulating the amount of feed of said shell.

6. In a device for cutting shells of metal, the combination ofcutter-disks, means for feeding a shell to said disks in order that itmay be cut into a continuous strip, a drum onto which said strip iswound, a spirally-arranged flange at one end of said drum for windingthe strip into a coil, and a removable liange at the opposite end of thedrum, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
